The nickel-based composite metal hydroxide for the lithium secondary battery positive electrode active material precursor and a method of manufacturing the same

The present invention relates to a spherical or a lithium secondary battery positive electrode active material precursor of a nickel-based composite metal hydroxide and a manufacturing method for an elliptical, and more particularly, nickel-based composite metal hydroxide is Co, Mn, Fe, Mg, Ti, Cu, Zn, and include Al, Ca, V, Cr, Mo of at least one element selected, in the manufacture by co-precipitation and then input the equivalent ratio of the precipitation agent / metal salt with at least 1.4, by adjusting the equivalent ratio to 0.4 or less nickel-base control increasing the average particle size of the composite metal hydroxide than 20㎛ to provide a method of manufacturing the nickel-based composite metal hydroxide of high thermal stability for a lithium secondary battery positive electrode active material precursor. Composite metal hydroxide, co-precipitation, nickel complex-based
